There is a solution here, which prioritizes capitals

But what I want is to have first cells where all letters are capitals, and then cells with lowercase or mixed case in a way that it would sort Greek text. I.e. like this

ΆΔΦΞ
ΓΦΞΘΓΗ
ΔΞΚΞ
ΈΓΦΞΚΞ
ΤΡΘΙΟΘ
ΦΘΟΙΘΔΙΘ
Άδφξ
γφξθγη
Δξκξ
Έγφξκξ
Τρθιοθ
φθοιθδιθ
